Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high System Prompt Leakage · line 11 Skill contains instructions that could directly expose system prompts, internal rules, or hidden instructions to users or external parties.Fix: Remove any instructions that reveal, print, or output system prompts or internal rules. System instructions should never be exposed to end users.
What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00073 | $0.03392 |
| Opus 5 | $0.00036 | $0.01696 |
| Sonnet 5 | $0.00015 | $0.00678 |
| Haiku 4.5 | $0.00007 | $0.00339 |
Grade A, and why
app-namer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 260 lines — stays where its author put it; the contents beside it link to each section on GitHub.
App Namer Skill
Takes an app idea or one-liner and produces a ranked shortlist of 5-8 validated name candidates — not random brainstorming. Each candidate is generated from a naming archetype, paired with a subtitle, checked against App Store display rules, and run through an availability gauntlet (App Store Connect name, trademark, domain, handle) before it's recommended.
The output is a name you can reserve in App Store Connect today, with the keyword work already aligned to feed the app-store/keyword-optimizer skill.
When This Skill Activates
Use this skill when the user:
- Has an app idea but no name ("what should I call it?")
- Wants name ideas or a naming brainstorm for a specific app
- Needs to know if a name is available / safe to use
- Is about to create the app record in App Store Connect and needs to reserve a name
- Wants to rename an existing app and needs ownable, ASO-smart options
- Picked an idea from
idea-generatorand needs the name before writing the PRD
No app idea yet? Run product/idea-generator first, then come back with the chosen idea.
Already have a locked name and just want ASO? Skip this skill — go to app-store/keyword-optimizer.
Reference Files
Before generating names, load both reference files:
| File | Purpose |
|---|---|
| naming-strategies.md | The 3 archetypes, naming techniques, App Store display mechanics (30-char limit, home-screen truncation, name/subtitle interplay), good/bad examples |
| validation-checklist.md | The knockout gauntlet — App Store Connect name availability, trademark sanity check, domain/.app, social handles, linguistic safety |
What This Skill Does
Idea/positioning
↓ elicit
Naming brief (what it does, who it's for, personality, scope ceiling)
↓ generate across archetypes
20-40 raw candidates (branded / descriptive / hybrid)
↓ filter (pronounce, spell, truncate, confusability)
8-12 survivors
↓ pair with subtitle + score
Ranked candidates with name + subtitle + display preview
↓ validate (ASC name / trademark / domain / handle)
5-8 validated candidates
↓
Recommendation + "reserve now" action
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

app-namer is a skill published in the GitHub repository rshankras/claude-code-apple-skills (719 stars, last pushed 1mo ago), licensed MIT. It adds 73 tokens to every session and 3,392 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
